Will the Core Ultra 5 245K bottleneck the RX 7600 XT?

No. At 1440p the RX 7600 XT is the limiting part, which is the normal state for a gaming PC. The Core Ultra 5 245K has headroom to spare. This is a model estimate from performance indexes, not a measured FPS loss.

What power supply do I need for a Core Ultra 5 245K and RX 7600 XT?

Sustained gaming load is about 432 W using the RX 7600 XT's measured draw. A 650 W unit is the safe choice; a good-quality 550 W unit also covers it.

Is this pair better at 1080p or 4K?

1080p: GPU-limited 16% (balanced). 1440p: GPU-limited 24% (GPU-bound (normal)). 4K: GPU-limited 41% (CPU overkill).

Core Ultra 5 245K + RX 7600 XT: bottleneck check

24%

GPU-limited at 1440p. GPU-bound (normal).

CPU GPU

The RX 7600 XT is the part working hardest at 1440p, which is what you want. The Core Ultra 5 245K keeps about 24% in reserve.

By resolution

Resolution	Limiting part	Severity	Verdict
1080p	GPU	16%	balanced
1440p	GPU	24%	GPU-bound (normal)
4K	GPU	41%	CPU overkill

The RX 7600 XT is the limit at every resolution and by a wide margin at 4K (41%). The Core Ultra 5 245K is overkill for this card: a faster GPU would give you far more frames than any CPU change.

Power supply

The RX 7600 XT measured 198 W average while gaming (238 W highest 20 ms spike, TechPowerUp). With the Core Ultra 5 245K at its maximum turbo power of 159 W and about 75 W for the rest of the system, the sustained load is about 432 W. A 650 W unit is the safe choice; a good-quality 550 W unit also covers the measured draw. Details on the RX 7600 XT PSU page or try other pairs in the PSU calculator.
